“The public is growing restless as they see the longer lines and they experience longer wait times,” Mayorkas said at the World Travel and Tourism Council Global Summit in Dallas. “We are working with the Department of Commerce in advancing a number of solutions and we are working with the private sector in doing so.” Here are some changes you can expect to roll out in the coming months.

Security screenings will continue to get a makeover.

After a Department of Homeland Security report noted that the Transportation Security Administration failed to detect threats in 67 of 70 security tests—including spotting undercover investigators moving through checkpoints with potential weapons—changes to security and screening procedures will continue to be reevaluated. Thousands of screeners across the country will also continue to be retrained in detecting weapons and other illegal items.

Two traveler programs may turn into one.

Though Global Entry and TSA PreCheck both allow passengers to go through expedited lines without removing laptops and liquids (or taking off their shoes), differences in the fees and application processes have caused some confusion. According to a recent Airfarewatchdog poll of 1,400 fliers (many of them frequent travelers), only 32 percent had signed up for Global Entry (which includes TSA PreCheck, as well as shorter lines at immigration), 26 percent had signed up just for TSA Precheck, and an astounding 23 percent didn't even know about these programs. (Meanwhile, 21 percent knew plenty—and didn't find them necessary.) That may soon change: “We have marketed those separately and I think we have to reconsider unifying their brand and frankly innovating more in our marketing of those endeavors so they are better known and our subscription levels only increase,” says Mayorkas. Should these changes occur, it would no doubt help to ease some of the clogged lines at airports.

Preclearance in foreign airports will increase.

At present, 15 foreign airports in six countries have personnel on site so travelers to the U.S. can go through customs before they board their flight, instead of when they arrive in the U.S. This helps to ease the glut of travelers so often found in those slow-moving customs lines. Ten new airports in nine countries were accepted last year for possible preclearance, and the DHS will ramp up its solicitation efforts in the coming months. “This is a significant priority of ours now in the Department of Homeland Security,” says Mayorkas.

Airport pre-checkpoint security will get a closer look.

The March attacks at Brussels's Zaventem airport comprised explosions near departure gates, exposing weaknesses in an airport's security before the screening process. “It is not just the screening of passengers that is of acute concern, but it is the airport as a destination, it is the airport as a location of mass assembly, that we must be acutely concerned about as well,” says Mayorkas. Already, in many airports in Africa, the Middle East, and Southeast Asia, passengers have to show identification, pass through metal detectors, and have their bags checked when entering the airport. And though a TSA employee on the condition of anonymity did confirm to Condé Nast Traveler that they are deploying additional security to major airports, time will reveal if permanent measures are put into place.
